FRALPJEE STRUCTURE FOR ROAD ROLLERS.

Application filed November 21, 1921, Serial No. 516,574.

To all whom it may concern:

Be it known that 1, ANDREW W. AITKEN, a citizen of the United States,residing at Springfield, in the county of Clark and State of Ohio, haveinvented certain new and use ful Improvements in Frame Structures forltoad Rollers, of which the following is a specification.

My invention relates to frame structures for road rollers.

The object of my invention is to provide a structure of this characterof such a nature as will provide a substantial support for the watertank and also a rigid point of attachment for a draw-bar and at the sametime be so arranged as to permit the ready removal of the rear axle whendesired.

In the accompanying drawings Figs. 1 and 3 represent, when placedtogether end to end, a top plan view of the st ructure.

Figs. 2 and 4:, when placed together end to end, represent a sideelevation of the same.

Fig. 5 is an enlarged vertical sectional view on the line 5-5 of Fig. 1.

Fig. 6 is an enlarged vertical section on the line 66 of Fig. 1.

deferring to the drawings, 1 and 2 represent steel vertically-disposedside plate members, the forward ends of which are projected upwardly andforwardly and carry the head 3 in which is journaled in the usual waythe swivelled king post for the forward roller. The upper edge of eachof these plates is reinforced by an angle-iron 4, these angle ironsbeing tied together by the bars Riveted to the lower edge of each ofthese side plates is a channel beam, 6 and 7, these beams being tiedtogether by the channel bars 8 and 9; the bars and the beams beingconnected together by the angle irons 10. Each of the side plates 1 and2 has an open ing 11 to receive the bearing for the rear axle theseopenings being within a short distance of the rear edges of therespective plates, each plate being slotted between the opening and itsrear edge as indicated at 11 whereby the axle may be removed whendesired.

The channel beams 6 and 7 are extended rearwardly beyond the rear edgesof the plates 1 and 2 and have bolted to their rear ends, through theangle irons 12, the water tank 13. The sides 13 of the water tank areextended beyond the front wall thereof, as

indicated at 13 and these extended edges are bolted to the rear ends ofthe side plates and 2 by bolts 1 1; a stiffening bar 15 being insertedbetween the heads of the bolts and the extended portions of the tank.

A draw bar 16 of any suitable form is attached to the rear ends of thebeams 6 and '7 by the angle irons 17, this draw bar being of nature toreceive the draft appliances of scarifying devices, or to which may behitched any other structure designed to be drawn by the roller.

the construction descrilzied it will be seen that a frame structure isprovided which will be of ample rigidity and strength to not onlysupport the operating parts of the roller and the water tank thereof,but also provides a rigid point of attachment for draft appliances sothat the tank may be re lieved of the strain which would beotherwise'impressed upon it by the attachment of such appliancesdirectly thereto as has been the custom. It will be seen that in theevent it is desired to remove the rear axle, this can be accomplishedreadily by removing the tankand then the axle through the slottedopenings.

Having thus described my invention, I claim 1. In a frame structure ofthe character described, a pair of vertically disposed side plates, apair of side beams connected there with, said plates having openings toreceive the rear axle, the beams being extended rearwardly beyond theplates, a tank removably supported from the beams and also removablyconnected with the rear edges of said plates, provision for theattachment of daft appliances to the rear ends of said beams, and meanswhereby the axle may be removed from said plates when said tank isremoved.

2. In a frame structure of the character described, a pair of bracedvertically-disposed side plates having openings to re ceive the rearaxle with slots leading from. the openings to the rear edges of saidplates, channel beams connected to the lower edges of said plates andprojecting rearwardly therefrom, and a tank reinovably secured to therear edges of said plates and also removably connected with the beams atpoints beyond the rear edges of ,the plates, the rear ends of said beamshaving provision for the attachment of draft appliances.
